I found it!
In the second picture, just above the left-hand bolt at the exhaust flange you can BARELY see another nut (almost in the shadow). It seems I missed tightening this all the way (this bolts to what I thought was the heat shied). I ran my finger up around the bolt and it seems it runs into the timing case cover area. I just tightened it up and hopefully that'll stop it
Thanks for all the advice. I'll report back with my hopefully good news of a stopped leak.

Great! If the leak does not stop it may be because you disturbed the sealing grommet under the bolt's washer. These grommets harden and leak over time like the valve cover gaskets. The good news it that they cost 86 cents a piece. I changed mine last winter and my cover has been bone dry since.

What could have happened is a slow leak from the valve cover dripping onto the heat shield. It pools up there and you don't know you have a leak. Once you lift the car at a certain angle it starts to drip down onto the heat exchanger. It could also be many other things too, I would check it asap.

Well, I'm fairly certain it was what I posted about above. The bolt/nut had fresh oil dripping from it. Tightened it up, wiped up the oil, and no more leak as of this morning after sitting over night
